Another suggestion:
change in the GCBOS template
Code:
<span style="float:right; padding-right:20px"><a href="#" onclick="gcbos.modifyHeight(-25);return false;">-</a><a href="#" onclick="gcbos.setHeight(175);return false;">/</a><a href="#" onclick="gcbos.modifyHeight(25);return false;">+</a></span>
to
Code:
<span style="float:right; padding-right:20px"><a style="color: {vb:stylevar forumbits_aForum};" href="#" onclick="gcbos.modifyHeight(-25);return false;">-</a> <a style="color: {vb:stylevar forumbits_aForum};" href="#" onclick="gcbos.setHeight(175);return false;">/</a> <a style="color: {vb:stylevar forumbits_aForum};" href="#" onclick="gcbos.modifyHeight(25);return false;">+</a></span>
Makes the -/+ the same colour as the forum title not the general link colour and puts a space in between the three characters to make them easier to click.
